The Eskimo Nebula (NGC 2392), also known as the Clown Face Nebula, Lion Nebula, [4] or Caldwell 39, is a bipolar [5] double-shell [6] planetary nebula (PN). It was discovered by astronomer William Herschel in 1787. The formation resembles a person's head surrounded by …

NGC 2392的“皮大衣”实际上是恒星的外部物质，正被每小时5万公里的风吹离死亡的星核。 随着外层物质的剥离，密集炙热的星核被超热气体包围。 宇航局称：“这个炙热 星核 的表面温度大约在5万摄氏度左右，正在速度更快的恒星风作用下喷射外层，速度达到每小时600万公里。 这颗炙热恒星产生的辐射以及快速和较慢恒星风之间的交互作用形成了一个行星状星云的复杂的丝状外壳。 最终，这颗恒星的残余将发生塌陷，变成一颗白矮星。 通过将钱德拉 X射线望远镜 在X射线条 …

2000年1月24日 · In its first glimpse of the heavens following the successful December 1999 servicing mission, NASA's Hubble Space Telescope has captured a majestic view of a planetary nebula, the glowing remains of a dying, Sun-like star. This stellar relic, NGC 2392, was first spied by William Herschel in 1787.

2010年4月6日 · This stellar relic, first spied by William Herschel in 1787, is nicknamed the Eskimo Nebula (NGC 2392) because, when viewed through ground-based telescopes, it resembles a face surrounded by a fur parka. In this Hubble telescope image, the 'parka' is really a disk of material embellished with a ring of comet-shaped objects.

NGC 2392 is a double-shelled planetary nebula, with the more distant gas having composed the outer layers of a Sun-like star only 10,000 years ago. The outer shell contains unusual light-year long orange filaments. The inner filaments visible are being ejected by strong wind of particles from the central star.

2000年1月24日 · NGC 2392 is about 5,000 light-years from Earth in the constellation Gemini. The picture was taken Jan. 10 and 11, 2000, with the Wide Field and Planetary Camera 2. The nebula's glowing gases produce the colors in this image: nitrogen (red), hydrogen (green), oxygen (blue), and helium (violet).

NGC 2392 (Caldwell 39, PK 197+17 1, PN G197.8+17.3, the Eskimo Nebula and others) is a planetary nebula located approximately 6,000 light-years away in Gemini. Imaged February 17th and 18th, 2025 from Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.

2013年7月11日 · NGC 2392, nicknamed the "Eskimo Nebula", is what astronomers call a planetary nebula. Stars like the Sun can become remarkably photogenic at the end of their life. A good example is NGC 2392, which is located about 4,200 light years from Earth.

ngc 2392 In its first glimpse of the heavens following the successful December 1999 servicing mission, the NASA / ESA Hubble Space Telescope has captured a majestic view of a planetary nebula, the glowing remains of a dying, Sun-like star.

2025年2月23日 · NGC 2392 is also called the ‘Clown-Faced Nebula.’. It is a small planetary nebula of glowing gas in Gemini. This object is about 6,500 light years away and can be seen in a small telescope. It’s small size (diameter is just 48 arcsec) makes it a …
